Speciiication of Letters Patent. Patented May 10, 1910.

Application filed May 29, 190 9. Serial No. ieaaz h To all whom it mayconcern:

Be it known that I, Enwm L. THOMAS, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Improvement in Fillers forAutomobile-Radiators, of which the following is a specification.

This invention relates'to fillers'which are arranged at the top ofautomobile radiators or coolers and through which the latter are filledwith water. Heretofore these fillers have generally been of circularform which rendered it difiicult, if not practically im-' possible, tofill the radiator through the same without spilling considerable water.To obviate this it has been proposed to construct the body-or funnel ofthe filler of oval form so as to adapt the same for receiving a widerstream of water from the pail whereby the water is being poured intothe'radiatorbut such a funnel is difiicult to maintain wate r tight andneat in appearance.

- The object of this invention is to rovide a filler for automobileradiators whic has a body or funnel of oval form and which has simple,elficient, and neat means for securely closing the same to prevent theescape of the water andalso to prevent the entrance of foreign matterinto the funnel from the exterior after the radiator has been filled.

In the accompanyin drawings: Figure l is a top plan view 0 my improvedautomobile radiator filler. Fig. 2 is a vertical longitudinal section ofthe same. Fig. 3 is a bottom plan view of the filler, on a reducedscale.

Similar letters of reference indic'ate corresponding parts throughoutthe several views.

A represents the top or roof of the water chamber or space of anautomobile radiator which has an inlet opening a. B the upwardly flaringbody or funnel of the filler the lower or small end I; of which is ofcircular form while its upper or large end 6 is of oblon or elongatedform, as shown in Fig. 3. he lower end of the funnel or body is securedto the top of the radiator in any suitable manner so that'the outlet 0in the bottom of the funnel is in line or registers with the inletopenin a of the water chambr of the radiator. ithin the bore of itsoutlet the funnel is provided with a lower circular rabbet forming anupwardly facing lower shoulder d and a cylindrical wall d and abovethislowerrabbet the bore of the outlet .-is provided with an upper.circular rabbet'of larger diameter than the lower rabbet and forming anupwardly facing up- G represents a circular stopper or plug whereby theoutlet of the funnel is closed and which has a lower contractedor narrowpart g adapted to engage the lower rabbet'in said outlet and anupperenlarged part gk whichengages the upper rabbet in said outa let and isprovided with an external screw thread which engages with the internalscrew thread of said upper rabbet. This stopper or plug is turned forsecuring the same in the'outlet of the funnel and remov ing the'sametherefrom by means of-anup right stem H projecting upwardly'from thestopper and provided at its upper end with a handle it for manipulatingthe same, the

latter being preferably inclosed by a shell 11 of heat insulatingmaterial suclr as fiber or,

rubber so that the hand will not be burned eign matter at this time isprevented from getting into the funnel and subsequently enter theradiator and interfere with its operation. This cover .alSo produces aneat arid finished appearance of the-top of the funnel. The cover is ofthe same oblong or elongated form as the upper end of the funnel andisprovided with :1 depending marginal llange' j which fits the marginalrabbet at the upper end of the funnel. The central part of the stempasses slidingly through a central opening 70 in the cover whereby thelatter 18 confined on the stemibetwecn the handleand stopper and theseparts are n'ermanentl y (:0nnected, so that they are siu'iultaneouslyapplied to and removed from the funnel. In order to prevent the coverfrom rattl ng while in use the same is yieldingly pressed against thefunnel by a tension device who is interposed between the stem and thecover and which preferably consists of a tubular casing or sleeve Lsurrounding the stem between the stopper and cover and provided at itslower end with a lower internal flange I which engages slidingly withthe stem while its upper end is provided with an up per external flangeZ which is secured to the underside of the cover by screws m, .as shownin Fig. 2 aspring N surrounding the stem and engaging at its lower endwith the lower flange Z of the sleeve,and a shoulder 0 having the formof a screw nut bearing against the upper-end of the spring and engagingwith a screw thread on the stefii immediately below the cover.

When the stopper andcover are removed from the funnel withthe stem andhandle the spring Nexpands until the screw nut 0 bears against thecover. When thus removed from the funnel the distance from the marginalbearing face of the cover and the bearing face of the stopper is lessthan the distance between the stopper and cover seats on the funnel. Itfollows from this that in applying the cover and stopper to i thefunnel, the cover engages with its seat stopper is seated on the lowerend of the on the upper end of the funnel before the funnel, wherebyupon screwing the stopper fully into engagement with its seat by thestem the shoulder or screw nut 0 will be carried downwardly away fromthe underside of the cover and increase the tension on the spring N,thereby causing the cover to be held yieldingly in engagement with thefunnel and preventing the same from-rattling.

I claim as my invention:
